Star Trek made the line that space was the final frontier famous. It is true. Everything humanity has ever done is contained on a tiny speck floating in space.
Carl Sagan called it the pale blue dot based on the image from the Voyager 1 spacecraft that was taken in 1990 when the craft had traveled about 6 billion kilometers from Earth, the picture of the galaxy included Earth which was no more than a speck on the image. Less than an hour later Voyager would shut down its camera never to take another image.
It took all of human history to get us to having the first person breach the bounds of gravity and orbit the Earth just once in 1961. Yuri Gagarin represented the first living thing that had taken billions of years of evolution to determine how to rise high enough above the Earth to remain there.
